Rational Approximation

AAA(f, r, *[, rtol, max_iter, ...])	Compute a rational approximation of a function using the continuum AAA algorithm.
poles_residues(z, f, w[, residue])	Compute the poles and residues of the rational function in barycentric form.
zeros(z, f, w)	Compute the zeros of the rational function in barycentric form.
evaluate(z, f, w, Z)	Evaluate the rational function in barycentric form at points Z.
derivative(z, f, w, Z, *[, k])	Evaluate the k-th derivative of the rational function in barycentric form at points Z.
